Fix a RAW partition

A RAW volume means Windows cannot recognize a usable file system there; it does not prove the data has been deleted.

Quick answer: A RAW volume means Windows cannot recognize a usable file system there; it does not prove the data has been deleted.

When this approach makes sense

Check GPT versus MBR, the current filesystem, whether Windows boots from this disk and any hardware/device compatibility requirements. This guide explains how to approach fix a raw partition without assuming every disk or license is identical.

How to proceed on Windows

  1. Step 1. Stop writing new data to the affected disk.
  2. Step 2. Check cables and the drive's hardware health, then capture Disk Management information.
  3. Step 3. Attempt read-only recovery or clone the failing drive before repairs.
  4. Step 4. Only format after files are safely recovered or confirmed unnecessary.
Important: Do not immediately format or initialize a disk if it contains data you need to recover. Back up important data to a different physical drive before changing a live partition or filesystem.

How to verify the result

Recovered files open correctly and the repaired or replaced drive passes health checks. Reopen Windows Disk Management to compare the resulting layout with the plan. If the operation involved the system disk, also confirm Windows starts and that your backup and recovery options remain available.

If the result is different

Stop and capture the error or unexpected disk map before retrying. Check the drive's health, file system, encryption status and available capacity. If files are missing or the disk appears RAW, avoid writing to the volume and consider an image-based recovery workflow.

Free versus paid edition

Some advanced functions, especially OS migration, boot media and data recovery, may require a paid edition. Verify the current MiniTool comparison page. This page does not claim every shown operation is included in every edition, and it does not claim to have tested a particular PC or storage device.

Frequently asked questions

How do I fix a RAW partition?

A RAW volume means Windows cannot recognize a usable file system there; it does not prove the data has been deleted. Start by checking the disk layout and creating a verified backup before applying any changes.

Can this operation cause data loss?

Yes, any partition or filesystem change can have risks from incorrect disk selection, power loss or hardware errors. Do not immediately format or initialize a disk if it contains data you need to recover.

How can I tell if the result is correct?

Recovered files open correctly and the repaired or replaced drive passes health checks.
